This hadith teaches us the importance of reciting a prayer before going to bed. The Prophet Muhammad ﷺ instructed us to dust off our beds with the edge of our garment three times and then recite this prayer “Bismika Rabbi Wada'tu janbi, wa bika arfa'hu. In amsakta nafsi faghfir laha, wa in arsaltaha fahfazha bima tahfaz bihi 'ibadaka-s-salihin” which translates to “In Your Name my Lord I lay down my side and in Your Name I raise it up again; if You should take away my soul then have mercy on it; and if You should return my soul then protect it with what You protect Your righteous servants”. This is an important reminder that we should always seek Allah's protection before going to sleep as He is the one who can truly protect us from any harm or danger that may come our way during the night. It also serves as a reminder that we are ultimately dependent on Allah for all things including life itself so we must always be mindful of Him and His commands even when we are asleep.
